Video
Generally, for best performance, the output resolution of your video source should match the
display's native resolution. See the display specifications in Appendix C to find your
Touchmonitor's native resolution. Operating in other resolutions will degrade video
performance. For further information about video resolutions, please refer to Appendix A.
For full APR touch functionality, the input video image should be fully scaled to the display's
native resolution.
Your Touchmonitor will likely not require video adjustments. However, for analog VGA video,
variations in video graphic card outputs may require touchmonitor adjustments through the
OSD to optimize the quality of the touchmonitor's displayed image. Also, to reduce the need
for adjustments for different video mode timings, the monitor correctly scales and displays some
of the video industry's most common video timing modes. Refer to Appendix C, Technical
Specifications, for a list of these Preset Video Modes.
